The combination of an applied force and a constant frictional forceproduces a constant total torque of 35.6N·m on a wheel rotating about a fixed axis. The appliedforce acts for 5.92 s. During this timethe angular speed of the wheel increases from 0 to 10.4 rad/s. The applied force is then removed, and thewheel comes to rest in 60.9 s.
